Okay.....so? Eight months from now, what are you going to be looking at instead? The same silly, obnoxious tubes you're staring at and grumbling at today. They're not going anywhere, you know that.
:duh:
You could also speed things along a little. Attach your moss to a pre-measured length of mesh and float it for a while. Scoot that around day by day so it won't shade too much below. It'll soak in a lot more light being so much closer to the surface and get established faster. It'll be fuzzy already in a month... and quite well filled in after two. Install it in place then after you won't care if the growth slows down a little. Besides, established moss grows faster than it does while it's still acclimating.
